Re: Using viruses in pen-test

["David Swafford" <dswafford () alterhighschool org>]

I wonder if there is some type of "fake" virus you could use in this case.  I know in a pen test you are hired to do 
the job asked, but I would hate for you to have to face your client after a "pen test gone bad" kind of situation where 
something backfired leaving the whole network in shambles from a massive virus outbreak.  Clients sometimes don't 
always understand what they are truly asking (ie. the impact it might cause).  I'm not sure how skilled you are at 
writing code but the option of writing a new virus which simulated something dangerous (but didn't actually damage 
anything valuable) might be a way to test to see if the anti-virus software doing its job on the "zero day" part (based 
on heuristic scanning).  

David.

Hi List,
I wish to know your views on "Using viruses in pen-test"I
I've been working in the infosec domain for over 2 years with a couple
of infosec certs including CEH and conducting pen-tests for my clients
for about a year.

My recent client has hired me for carrying out "every possible" type
of pen test.
This includes testing organizations defence mechanism against viruses
as well, this includes to test whether anti-virus administrators have
up-to-date virus definitions etc. I'm supposed to gather this
information by means of thorough penetration tests only.

As we all are aware that how the viruses (worms/trojans included)
enter into  the corporate network propagate over LAN. There are many
ways like email attachments or infected content brought in by
employee.It spreads on itself thereafter.

Now my question:

Is there any standard procedure to test the posture of organizations
network security against potential virus threats? I mean i wish to
know about pen-test carried out against Antivirus-product. In order to
replicate itself, a virus must be permitted to execute code and/or
write to memory. Thus this pen-test should also tests that.
And do I need to use some known viruses for this kind of pen-test?

Have your thoughts on this topic please.
Thanking you all.
